.T all whom it may concern: 7

Be itknown that I, CHARLES CHEVAILLER, acitizen of the Republic ofFrance, residing at l Rutland street, Regent, London, N. W., England,have invented a new and" useful. Device for Repeating on the Engine theSignals Given onthe Line, of which the fol lowing is a specification.

This invention relates to a device for repeating on the enginethe'signals givenon the line. The signals are repeatedin' front of theengineer and of the stokerwho thus are immediately informed of theposition occupied by the semaphore, the round'disk or the square disk,Whatever may be the weather, however badly the disk may be lighted, andforwhatever reason the signal 1 itself could notbeseen by the engineer.

' the signals.

This device has the advantage that it does not require any alteration inthe lining or any transformation of the signals. The apparatus does notcomprise a signal whistle which is a further advantage, since with anordinary whistle the engineer relies too much on it and consequentlyneglects to watch the signals.

The device consists of two windows, a white one and a red one mounted onthe windscreen of the engine. The windows are uncovered according to theposition of If the line is blocked thered window is uncovered and thewhite is covered and inversely if the line is clear.

' The device for obturatingthe windows is controlled 'by compressed airsent out by rubber balls which are compressed by rods under the engine.This lever is-operated by a trip devicesituated betweenthe, rails andarranged at least 200 meters inrear of the signal from which it isoperated itself.

A-lantern is mounted on "the line to indicate the 1 place where "the"apparatus is mounted so that, if the-signals are not visible the enginedriver knows where they are.

In the accompanying drawings-the inven tionis shown by' way of exampleFigure 1 is a perspective view of a line with trip devices for repeatingthe signals on the engine. I v

Fig. 2 is a cross section of Fig. 1 the trip device being inthe'positioii which it assumes'when the line is free orclear, Fig. 3 isa similar view which shows the device in the position which it' assumeswhen the line is blocked.

' Fig. 4 is a section on line 4:4 of Fig. 1. Fig. 5 is a front view ofthe wind screen with the red and white windows.

Fig. 6 shows the apparatus operating one of the obturators. Between therails 1', 2 a trip device 3 is arranged adapted to pivot around an axlei. This trip device 3 is liftedbymeans of two connecting rods 5, 6. Theconnecting rod 6 is fixed on a shaft 7 which is mounted in bearings andis operated by the same apparatus which operates the signal to berepeated. On this shaft a lever 8 is fixed which has a counterweight 9maintaining the lever in determined positions. This trip device 3 ispreferably situated at the right of the line and it is provided alone ifonly the signals of the semaphore are to be repeated, but if also thesignals of the round or square disk are to be repeated, which indicateslacken speed or stop respectively, two trip devices are arranged, oneat the rightand the other at the left of the line. The second device isof similar construction to the first one and it further has an abutment10, articulated at an axle 11 adapted to be maintained in liftedposition by two of the lever 16 pivotally mounted on an axle 17 which"is fixed in a support 18 under the engine. The lever 16 is preferablyprovided with inclined surfaces 14,15 at the end, the inclinecorresponding'with the slope. of the abutments 3 and 10 to serve forsoftening or decreasing the shock when the lever comes in contact withthe trip devices. The ends of the lever 16 carry rods 19, 19 with largeheads 20. Above the heads 20 rubber balls 21 are mounted which areconnected'by hose or conduits22 with the obturating devices for thewhite window 23 and red Window 24.

The rods 19, 19 (see Fig. 6) are located in tubular sliding pieces orguide tubes 25 in which saidrods can move, the movement of the rodsbeing braked by means of blade springs 26 which bear against the innerwall of said tube 25. The blade springs prevent the accidentaldisplacement of the rod.

The device for showing the signals in the cab is shown in Fig. 5 andcomprises a lamp 27 located in a box 28 provided with a white window 23and a red window 24. Arranged to slide between the lamp burner and thewindows is a door or obturator 30 large enough to cover either of thewindows while uncovering the other. Atthe lower end of the door arefixed impact blocks 32 for moving the door. Fixed to the box 28 arecylinders 3 3 with which the hose connections 22 are in communicationand these cylinders are provided with plungers 31- which are operated bythe air which is compressed by the action of the rods 19, 19 on theircorresponding balls 21, (see Figs. 2 and'G) and are thus caused tostrike against the blocks 32, driving the door 30 from its positionclosing one window to the opposite end closing the other window.

When the semaphore is operated, the lever 8 is actuated upon at the sametime by means of a device similar to the tongue of a switch whereby theshaft 7 is rotated and consequently the connecting rod 6, fixed on saidshaft is actuated. In moving, the connecting rod 6 assumes an almostvertical position and draws along the connecting rod 5 whereby the tripdevice is lifted. If now an engine which is fitted with the devicehereinbefore described moves over the trip device,the inclined surface14: which is in its lower position, strikes against the trip device 3which is lifted, so that the lever 16 swings around the axle 17 andlifts the rod 19, the head 20 of which compresses the rubber ball 21.The air forced out of the rubber ball operates the obturator whichuncovers the red window 24 and covers the white window 23. The enginedriver can thus see at once that the line is blocked and has time enoughto observe the semaphore before the engine arrives at the signal so thatthespeed of the engine can be reduced and if the line is still blockedwhen the engine arrives at the round disk the inclined surface willstill be lifted and consequently the red window will be still uncovered.The engine can slowly continue until it arrives at the square disk whereit will stop. If, however, the square disk is in the open position thetrip device 3 of this disk is lowered and the trip device 10 :lifted sothat the in clined surface 15, will come in contact with. the trip 10 sothat the lever 16 swings and the obturator is operated so that it coversthe red window and uncovers the white window, the line being free theengine drivercan continue atfull speed.
